Study of the maximum track density in proton-proton collisions at 13 TeV in CMS experiment at Large Hadron Collider at CERN

The high-density fluctuations in rapidity and pseudo-rapidity spaces are important when trying to study the connection between the hot hadronic matter and heavy ions collisions. In CMS experiment, we will analyze Run II data collected between June 2015 and December 2018 for proton-proton collisions at the center of mass energy 13 TeV. The data that we are going to analyze come from high multiplicity trigger. For Run II data, there are different types of high multiplicity triggers. The difference between them are because of transverse momentum pT, total number of tracks in an event, or total transverse energy ET. We will study of the maximum track density. We also will use Monte Carlo simulations (MC) to generate events and then compare with the real data.
